Overall it is a better player than the DX100....it wins in every category except SQ. I still believe after all the back and forth listening (I listen to the DX100 @ work and DX50 when I'm loungin @ home), the DX50 is about 60-70% unamped compared to the DX100 unamped with the same IEMs. It is a knock out (no brainer) @ the current price. I think iBasso could raise the price by a $100 and it'd still be worth it....maybe it's in the books after they iron out the bugs with more finalized firmware.

I do, but it's when I turn the screen off using the on/off button. More obvious on low and high gain with a bit of fluctuating chalkboard scratching noises. Mid gain it's softer and doesn't fluctuate, but still a high pitch whine. Disappears when the screen is on, or when I leave the screen off for a little while. Not really noticeable compared to the background white noise when music is playing

I think ER4S sound decent with DX50, specifically in centre channel depth and detail, however for an IEM that already has quite a narrow soundstage it can suffer a little. Another thing I've noted is there's a lack of air which is really noticeable when you switch between DX50 then Studio V with the Etys. Overall it's a pleasant sound which makes the ER4S rather versatile to many genres, however I still cannot beat the Studio V paired with ER4S providing the right genres are used for detail extension, soundstage, spaciousness and mid range coherency.

I think the DX50 sounds good with the right pairing, but there's four things it could improve on imo.

This is Head-Fi and I just stated that a $239 DAP is an overall better product than a $830 DAP. I'm pretty sure someone will come along to tell me that I have tin ears, the wrong source files, bad cables, poor synergy and that I should have been using WAV vinyl rips, not FLAC files.

Well I was branded as turning my back to my headfi brethren and branded a traitor by selling my AK120 to "downgrade" to dx50.... I m burning in my eternal hell now!!

Seriously dx50 isn't without flaws but for the cheap price (relatively to certain brand ) it is a no brainer. OTOH x3 is also keep improving its formware and features. Hopefully we will get more and better products at reasonable prices going forward.

I emailed Ibasso customer service. I made the 4th batch cutoff. Shipping on the 27th they said.

Olanzky. Please let me welcome to Head-fi. Sorry for your wallet.

I got the paypal receipt, but no other notification. My research says that is normal.

I'm not sure about shipping, though.

Can anyone comment on shipping notification? Do they absolutely send you a shipping notification, or does it depend on where you live in the world and what shipping company? I know some received shipping note, but I thought I read where others did not and had to ask.

I got one a day after they shipped it.
Some people have had theirs arrive before they got the shipping notification.

I had to ask, on shipping day I sent them an email requesting a tracking number and got it with a link to the courier (maybe just the name). They used DHL and it's in the US. In my experience with them the delivery takes about 3 working days. The box looks like an expensive chocolate box and inside, well the tasty dap Edited by musicheaven - 9/25/13 at 4:12am

I think they said it is because of the amp section and it can't be solved with firmware updates or something. Users either sold the dap or get a habit to turn it on before plugging in iems/headphones

@Sorensiim is right, I had a long discussion with Justin Wilson of HeadAmp about the exact same issue I.e. the popping sound from the Pico Slim which also uses the digital pot and he said it's a trade off, if he adds circuitry to remove the pop it will affect the amp performance. You get used to plugging the headphones/iems before switching the unit on and I prefer it performing to it's best.
